{"cve":"CVE-2022-29172","nvd":{"published":"2022-05-05T23:15:09.150","modified":"2026-06-17T04:39:44.450","status":"Modified","description":"Auth0 is an authentication broker that supports both social and enterprise identity providers, including Active Directory, LDAP, Google Apps, and Salesforce. In versions before `11.33.0`, when the “additional signup fields” feature [is configured](https://github.com/auth0/lock#additional-sign-up-fields), a malicious actor can inject invalidated HTML code into these additional fields, which is then stored in the service `user_metdata` payload (using the `name` property). Verification emails, when applicable, are generated using this metadata. It is therefor possible for an actor to craft a malicious link by injecting HTML, which is then rendered as the recipient's name within the delivered email template. You are impacted by this vulnerability if you are using `auth0-lock` version `11.32.2` or lower and are using the “additional signup fields” feature in your application. Upgrade to version `11.33.0`.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/auth0/lock/commit/79ae557d331274b114848150f19832ae341771b1","https://github.com/auth0/lock/security/advisories/GHSA-7ww6-75fj-jcj7","https://github.com/auth0/lock/commit/79ae557d331274b114848150f19832ae341771b1","https://github.com/auth0/lock/security/advisories/GHSA-7ww6-75fj-jcj7"],"products":["auth0:lock"],"source":"nvd","synced_at":"2026-10-19T21:31:59.322382750+00:00"},"epss":{"cve":"CVE-2022-29172","score":0.00622,"percentile":0.49859,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7ww6-75fj-jcj7","url":"https://osv.dev/vulnerability/GHSA-7ww6-75fj-jcj7","summary":"Cross-site Scripting in Auth0 Lock","modified":"2023-11-08T04:09:08.744522Z","packages":[{"ecosystem":"npm","name":"auth0-lock","purl":"pkg:npm/auth0-lock","ranges":["<11.33.0"],"fixed":["11.33.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
